The invention relates to furnace and analogous walls in geneml and the present disclosure is directed to an air-cooled wall.

Walls of this type usually embody inner and outer walls spaced apart to allow travel of air between them, and the present invention relates to the inner wall.

The object of the invention is to provide a wall construction which may be easily and m economically constructed, will be durable and will readily allow repair, novel provision being made whereby any portion of the wall may be disassembled to remove injured blocks 7 or bricks, without the necessity of molesting adjacent wall portions.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

I Fig. 1 is a sectional perspective view with a number of the bricks and blocks omitted, a double wall construction being illustrated in this view, with the outer wall formed of sheet material.

Fig. 2 is a horizontal sectional view thro h a corner of a well constructed in accor ance with Fig. l.

V Fig. 3 is a view similar to Fig. 2 but illustrating the outer well constructed from brick.

Fi 4 is a perspective view of one of the base locks.

Fig. 5 is a perspective view of one of the crown blocks.

in the drawings above briefly described, the numerals 6 denote a plurality oflattice columns 'to-the outer edges of which an outer wall 7 of sheet material, or an out-er wall 8 of brick or the like, may be secured. Secured to the inner edges of the columns 6, are a plurality of vertically spaced pairs of horizontal bars 9 and 10. Each bar '9 is of angle metal form and has its vertical flange portion secured by rivets or the like 11 to the columns 6, the base portion 12 of said her 9 projecting horizontally away from said columns an W being provided with a downwardly project 7 ihg'hn? dinai flan 13. Each bar 10 is secured yrivets or time 11' to'the beams 6 in'upwardly spaced relation with the subjacent bar 9, and said bar 10 embodies portions 12' and 13 which are identical with the portions 12 and 13 of the bar 9.

Each of the bars 9 supports a horizontal row of substantially rectangular, refractory, base blocks 14 having registering grooves 15 7 extending across their upper sides, nearone end. The blocks 14 seat snuglyin the angle of the bar 9. and their grooves 15 loosely receive the flange 13 of the superposed key bar 10, but the shoulders formedb one side of said grooves 15, abut said ange 13'. When engaging theblocks '14 with the bars 9 and 10, said blocks are positioned one at a time so that'they decline toward the space between the bars 9 and 10. The groove 15 of the block is then initially engaged withthe flange 13', and the block is canted irom its inclined position to al horizontal position, whereupon it snugly seats in the angle of the bar 9 and its groove 15 becomes interlocked with the flange 13.

Refractory brick-work 16 whose'bricks are l preferably of conventional form, is laid upon the base blocks 14 and the baseflange 12 of the bar 10 and refractory crown blocks 17 are laid upon said brick-work, said blocks 17 having registering grooves 15' which are engaged with the flange 13 of the superposed bar 9, in the same manner as the grooves 15 0 i are engaged with the flange 13' of the key bar 10, one wall of each groove 15 constitutiug a'shoulder abutting said flange 13.

The space between any bar 9 and the subjacent bar 10, is filled with a row of the base 35 blocks 14, the brick-work 16, and a rowof the crown blocks 17. and as said base blocks are eil'ectively interlocked with the adjacent bar 10 and said crown blocks are similarly interlocked with the superposed bar 9, these so bars efiectively key the upper and lower pprtions of the assemblage 14 -16-17, in p ace. 7

Immediately over any row of crown blocks 17, is a row of the base blocks 14, and these 911' dblocks 14 and 17 are preferably stepped at their adjacent faces, as shown, and of such dimensions as to provide a space which may be filled with asbestos or 'the'like 18, compens-ating for expansion and contraction. 1 1

By providing the novel construction shown and described, the wall may be easily, rapid ly and inexpensively constructed, a large part of said wall being formed from convent-ional fire brick, instead of forming the wall in its entirety from specially constructed blocks, as is usually done. Hence, a great saving in cost of installation is efiected and moreover, the wall may be more easily laid without skilled labor. Whenever any portion of the wall becomes damaged, this portion may be readily removed without disturbing adjacent portions, and new blocks or bricks substituted, allowing the quick and expeditious making of repairs.

The various details shown and described, are preferably followed. However, within the scope of the invention as claimed, numerous variationslnay be made, and it will be understood that although the wall formed by the parts 14, 16 and 17 and their securing means, herein constitutes an inner wall for adoublwwalled structure, it might well be used independently of an outer wall.

I claim:

1. In a furnace wall, a horizontal row of base blocks and a fixed horizontal angle metal bar in whose angle said blocks rest, said blocks having alined vertical shoulders at their upper sides facing away from the vertical flange of said angle metal bar, a

fixed horizontal angle metal key bar whose base flange overlies said base blocks and is provided with a downwardly projecting longitudinal flange abutting said I shoulders, brick-work resting upon said base blocks and said base flange of said key bar, a horizontal row of crown blocks resting upon said brickaboveand parallel with said angle metal supporting bar, said key bar having downwardly projecting block-engaging rigid means, and a block adapted to seat in the angle of said angle metal bar, the upper side of said block having means adapted to interlock with said downwardly projecting rigid means only when the latter and the block'- carried means are initially engaged and said block canted from an inclined position to a horizontal position.

4. In a furnace wall, a block-supporting frame-work embodying a pair of horizontal vertically spaced bars, the uppermost bar of said pair being provided with downwardly projectingrigid means adapted to interlock with wall blocks, the lower bar of said pair being of angular cross section to provide a seat for the blocks when the latter are initially engaged with said rigid means and canted from inclined to horizontal ositions.

In testimony whereof have hereunto aiiixed my signature.

2. In a furnace wall, a horizontal row of base blocks and a fixed horizontal angle metal bar-in whose angle said blocks rest, the upper sides of said blocks having registering grooves, a fixed horizontal angle metal key bar whose base overlies said base blocks and is provided with a downwardly projecting longitudinal fiange interlocked with said grooves, brick-work resting upon said base blocks and said base of said key bar, a horizontal row of crown blocks resting upon said brick-work and having registering grooves in their upper sides, and a second fixed horizontal angle metal key bar whose base overlies said crown blocks and is provided with a downwardly projecting longitudinal flange interlocked with the grooves of said crown blocks.

3. In a furnace wall, a fixed lower angle metal block-supporting bar, a fixed key bar
